Patent GB-479279-A (GB)
Abstract: 479,279. Bearings. SPERRY GYROSCOPE CO., Inc. May 29, 1936, No. 15269. Convention date, May 31, 1935. Addition to 474,629. [Class 12 (i)] [Also in Group XX] At least one of the angularly movable members of a gyroscopic instrument, such as a directional gyro or gyro compass, is peripherally supported by an air film maintained between co-operating surfaces which permit movement only about a desired axis. In the directional gyro shown in Fig. 1 the rotor 13 has spherical cavities which cooperate with buttons 14 secured to a ring 11 to form air flotation bearings. The periphery of the ring 11 has a convex outer surface which fits closely but loosely in a channel in the inner surface of a ring 9. The latter carries at the top and bottom spherical buttons 7, 8, which cooperate with cavities fixed to the outer casing 1 to form air flotation bearings to enable the ring 9 to turn about a vertical axis. Air is withdrawn from the casing 1 through the pipe 2 and is replaced by air drawn in through channels 3, 4. Part of this air supplies the bearings 7, 8 and part passes through bores 12 into a channel 15 between the rings 9, 11. From this channel part of the air floats the ring 11 within the ring 9, part passes through bores 16 and floats the rotor 13, and part passes through inclined bores in the ring 11 to form driving jets for the rotor. In a modification, Fig. 5, the rotor is in the form of a ring peripherally supported in cups 35, 36 fixed to the ring 11. An indicating card 19, .Fig. 1, is fixed to a member 21 rotatably mounted on air flotation bearings between the blocks 24, 25. The member 21 is normally engaged and driven by a ring 22 fixed to the vertical ring 9 but may be rocked out of engagement by pushing in the knob 30 so that the conical collar 32 engages the member 21. By turning the knob 30 the member 21 and card 19 may be reset without disturbing the gyro. Fig. 6 shows a gyro compass comprising an arrangement as shown in Fig. 5, but with a mercury bottle gravitational control 45, 46, 47 fixed to the ring 11 and with the ring 9 rigidly secured within an outer horizontal ring 50 which is floated in peripheral air bearings in a ring 51 hung from the gimbal ring 48.

Abstract: 1326226 Multiple flash device AGFAGEVAERT AG 13 Oct 1970 [16 Oct 1969] 48614/70 Heading H2H A multiple flash device 5, suitable for connection to a capacitor 3 chargable from a source 1 comprises a plurality of single ignition flashlamps 6-8 the resistances of which are reduced by ignition, each lamp being connected to an associated circuit breaking element 9-11, the lamps being in series with one another and each lamp and circuit breaking element except the first being in parallel with the element associated with the preceding lamp of the series. The circuit breaking elements are preferably fuses adapted to be ruptured by the heat of combustion of the associated lamps, the fuses preferably being included each as a part of a lamp. In use, upon closing the switch 4, the capacitor 3 discharges via the lamp 6 and element 9 and causes ignition of the lamp, the other lamps being shorted out by the element 9, which subsequently presents an open circuit owing to its rupture. Upon closing the switch 4 on a second occasion, the capacitor discharges through the lamp 7, via the previously ignited lamp 6, and the element 10. A testing circuit is provided whereby upon closure of a switch 12, a lamp 13 is ignited and the element 11 and therefore the lamp 8 are unused. In a modification, Fig. 2 (not shown), each lamp (20)-(22) is connected in parallel with the circuit breaking element (23)-(25) of the preceding lamp (19)-(21), the lamps being connected in series and also the circuit breaking elements being in series with one another.

Title: Spark ignition systems for internal combustion engines
IPC: F02P3/045
Filed: 1973-10-19
Abstract: 1489568 Ignition systems LUCAS ELECTRICAL Ltd 9 Oct 1974 [19 Oct 1973] 48845/73 Heading F1B An I.C. engine ignition system comprises a variable reluctance pick-up 110 producing output pulses when sparks are to be produced and feeding the pulses to a control circuit including a saturating amplifier, e.g. transistors 108 to 131, which results in the production of a spark when it de-saturates, but which, to minimize the risk of spurious signals in the pick-up producing a spark, is not saturated by spurious signals, a negative feedback path provided by capacitor 143 and resistor 144 ensuring slow saturation and relatively rapid de-saturation. The circuit consists essentially of an amplifier and a saturating amplifier, the former providing a negative signal to the ignition drive circuit 186, including transistor switch 163 and the ignition coil 165, until the latter saturates. Transistors 108 to 131 constitute an "operational amplifier" having a transfer function determined by capacitor 143 and resistors 109, 144 which give the amplifier a proportional plus integral response to input signals, the high frequency gain being insufficient to enable spurious signals to cause transistor 131 to turn off. Again, Fig. 3 (not shown), an alternative amplifier is described.

Abstract: 1,094,573. Linear dimension gauge. SHEFFIELD CORPORATION. Dec. 7, 1964 [Dec. 16, 1963], No.49760/64. Headings G1M and G1N. A linear dimension gauge comprises feeler arms 15, 16 (Fig. 1) mounted on blocks 12, 13, respectively, which are supported on rods 22-25, 30-35 (Fig. 5) for limited yielding movement parallel to a base 11, the arms extending through a slot 17 in a workpiece supporting table 20. The arm 16 is fixed to a carrier 36 and means are provided to selectively clamp the carrier to the block 13 depending on the size of the workpiece. The carrier 36 carries a magnifying glass 55 having a cursor line which co-operates with a linear scale 57 to obtain a measurement of the spacing between arms 15, 16 and the workpiece dimension. A known type electrical transducer 47 senses any variation in the spacing between blocks 12 and 13 from a mutual fiducial position and produces a corresponding signal which is fed through a selector switch to a meter 46. The value indicated on the meter is then added algebraically to the value read on the scale 57 to obtain the correct measurement of the workpiece dimension. A further electrical transducer 42 is provided to establish a reference vertical or fiducial position for arm 15 with respect to the base 11, one component of the transducer being fixed to block 12 and the other to base 11. During a setting up procedure the transducer 42 output is switched to the meter 46 to ascertain the reference value which is subsequently checked periodically during a measuring operation. The blocks 12, 13 are urged toward one another by a tension spring when measuring external dimensions and are urged apart by a compression spring for internal dimensions.

Abstract: 1403506 Circuits for charging capacitors COMPAGNIE GENERALE D'ELECTRICITE 30 Oct 1973 [3 Nov 1972] 50457/73 Addition to 1403307 Heading H2H [Also in Division H3] A circuit for charging a capacitor 101 as described in the parent Specification is modified so that the threshold circuit 126 is initially responsive to the charging current fed to the coil 103 exceeding a high threshold level to successively increase the capacitor voltage by large increments until a first predetermined capacitor voltage is reached whereupon the threshold circuit responds to the coil charging current exceeding a low threshold level to enable the capacitor voltage to be successively increased by small increments until the capacitor reaches the desired voltage. A thyristor 121 controls the state of transistors 108, 117 as described in the parent Specification, the voltage at the junction of a resistor 135 with a diode 134 increasing as the voltage across a resistor 125 increases to switch on a transistor 137 which switches off a transistor 140. The thyristor R1 is therefore triggered and switches off the transistors 117, 108 to enable a charge to be supplied from the coil winding 106 to the capacitor 101. When the capacitor voltage reaches the first predetermined voltage, the equality of the voltages at terminals a, b of an amplifier 149 enables the amplifier output to switch on transistors 155, 157 thereby connecting a resistor 158 in parallel with the resistor 135. The current through, and therefore the voltage across, the diode 134 is increased thereby enabling the threshold circuit to respond to lower coil charging currents flowing in the resistor 125. The capacitor 101 therefore continues to be charged with successive, reduced voltage increments until the desired voltage is reached whereupon the equality of the voltages at terminals a<SP>1</SP>, b<SP>1</SP> of an amplifier 159 enables the amplifier output to switch on a transistor 163 which switches off the transistors 117, 108.
